INSTALLATION INSTRUCTIONS

PLEASE study these instructions carefully before beginning this installation. Most installations can be accomplished with common tools and

procedures. However, you should be familiar with and comfortable working on your vehicle. If you do not feel comfortable performing this installation,

it is recommended to have the installation completed by a qualified mechanic. If you have any questions, please call our Technical Hotline at:

1-800-416-8628, 7:00 am - 5:00 pm, Pacific Standard Time, Monday through Friday.

IMPORTANT NOTE: Proper installation is the responsibility of the installer. Improper installation

will void your warranty and may result in poor performance and engine or vehicle damage.

DESCRIPTION: Edelbrock e-210 Cylinder Heads are designed for street/strip high performance use on non-emissions vehicles. These heads DO NOT

retain an exhaust crossover passage, and will not work on any vehicle requiring EGR (Exhaust Gas Recirculation) equipment. Edelbrock cylinder heads

feature intake and exhaust port openings that are CNC machine “matched” (to recommended gaskets) and have been designed for maximum flow

velocity when matched with Edelbrock intake manifolds, camshafts, carburetors, or additional recommended performance parts.

APPLICATIONS: The E-210 cylinder heads feature larger intake ports than comparable RPM heads and have been designed for applications

where increased performance is desired while maintaining compatibility with off-the-shelf parts. They are appropriate for any 327 ci or larger

small block Chevrolet engine built from 1955 to 1986 that does not need to meet emission requirements. They can also be used on 1987 and

later engines, provided that the intake manifold and valve covers are exchanged for those using the earlier bolt patterns. Use caution when using

these heads in combination with stock pistons and a high lift camshaft, as the larger valves may require clearancing the valve reliefs.

Complete cylinder heads are assembled with the following components: Stainless steel, one-piece, swirl-polished intake and exhaust valves with

under-cut stems for increased flow; 2-ring positive-oil-control seals; 3/8” rocker arm studs and 5/16” guide plates; Hardened steel valve spring

locators; Edelbrock Sure-Seat Valve Springs, retainers, and valve keepers.

NOTE: Complete cylinder heads are assembled and prepared for installation right out of the box. Bare cylinder heads will have valve

guides and seats installed, but will require final guide sizing and a valve job to match the valves you will be using.

IMPORTANT NOTES: READ BEFORE BEGINNING INSTALLATION!

For a successful installation, Edelbrock E-210 Cylinder Heads require

some components other than original equipment parts. To complete your

installation, you will need the following items:

❑ Head gaskets; Edelbrock #7310

❑ Intake manifold gaskets; Fel-Pro #1206

❑ Exhaust gaskets; Fel-Pro #1405

❑ Valve Cover gaskets; Edelbrock #7549

❑ Edelbrock head bolt kit #8550 (see instructions below)

❑ 14mm x 3/4” reach x 5/8” hex, gasketed spark plugs (heat

range to be determined by specific application)

❑ Adjustable rocker arm assembly (Premium roller rockers

recommended)

❑ +.100" longer-than-stock hardened pushrods;

Edelbrock #9629

PISTON-TO-CYLINDER HEAD CLEARANCE: Edelbrock cylinder heads

are designed for use with flat-top pistons. The use of domed pistons

requires that piston-to-head clearance be checked before installation.

Recommended minimum piston-to-head clearance is .050".

CHECKING VALVE-TO-PISTON CLEARANCE: Prior to installation, it is

highly recommended that valve-to-piston clearances are checked and

corrected to minimum specs, if necessary. Minimum intake valve

clearance should be .100”. Minimum exhaust valve clearance should be

.110”. E-210 heads come with larger than stock valves, which may

require additional clearancing of the valve reliefs on the pistons.

VALVE-TO-BORE CLEARANCE: Edelbrock cylinder heads are designed

to be used on engines with a minimum bore size of 4.000”. If used on

engines with a bore size less than 4.000" (307, 305, 283, 267, 265, &

262 c.i.d.), do not use a camshaft with more than .450" lift or the valves

may hit the cylinder bores.

ROCKER GEOMETRY: Rocker geometry should be checked, making

sure that the contact point of the roller (or pad on a stock rocker arm)

remains properly on the valve tip and does not roll off the edge. Visual

inspection of the rockers, valve springs, retainers, and pushrods should

be made to ensure that none of these components come into improper

contact with each other. If problems with valve train geometry occur,

changes such as pushrod length may have to be made.

ACCESSORIES

Although Edelbrock E-210 cylinder heads will accept OEM components (rocker arms, valve covers, intake manifold, head bolts, etc.), we highly

recommend that premium quality hardware be used with your new heads.

Intake Manifold: Most standard intake manifolds will fit, however

Edelbrock E-210 cylinder heads are matched in size and operating range

with Edelbrock Victor Jr. intake manifold #2975, Victor Jr. Port-Matched

#2900 or Super Victor #2925. Carefully inspect the intake flange when

using manifolds other than those recommended to ensure that the

manifold fully covers the larger than stock intake port on the head. Fel-

Pro intake manifold gasket #1206 is recommended. Apply Gasga-cinch

Edelbrock #9300 to intake surface of heads, manifold, and both sides of

intake gasket. Do not use cork or rubber end seals supplied with

gaskets; instead use RTV silicone sealer. Apply a ¼” bead along front and

rear of block, overlapping gaskets at the four corners. Torque intake

manifold bolts to 25 ft./lbs.

Head Bolts or Studs: High quality head studs or head bolts with

hardened washers must be used to prevent galling of the aluminum bolt

bosses. We recommend Edelbrock Head Bolt Kit #8550. OEM head bolts

may be used if they meet these specs for length: 1-3/4" (short bolts); 3"

(medium bolts); 3-13/16" (long bolts). Shorter bolts do not have enough

thread engagement for use with hardened washers. With OEM bolts, use

hardened GM #10051155, ARP #200-8511, or equivalent washers. Bolt

threads, underside of bolt heads, and washers should be lubricated with

an oil/moly mix prior to installation and torquing.

Valve Springs: #5085 complete cylinder heads are assembled with

valve springs that are compatible with Edelbrock Performer and

Performer RPM hydraulic flat tappet camshafts and lifters. If any other

camshaft is used, check with the camshaft manufacturer for

recommended valve spring pressures. The #5087 complete cylinder

heads come with valve springs designed for use with Performer RPM

Hydraulic Roller and mechanical flat tappet camshafts and lifters and

may cause engine damage if used with camshaft & lifter combinations

designed for lower spring pressures.

NOTE: If valve springs are changed to achieve more spring

pressures it will be necessary to also change rocker studs.

Spark Plugs: Use 14mm x 3/4" reach gasketed spark plugs. Heat

range may vary by application, but we recommend Champion RC-12YC

(or equivalent) for most applications. Champion RC-12YC are 1/4"

shorter than “N” series plugs and may be required for header clearance.

Use anti-seize on the plug threads to prevent galling in the cylinder head,

and torque to 10 ft./lbs. NOTE: Do not overtighten sparkplugs!

Valve Covers: Edelbrock cylinder heads accept stock valve covers for

the year and model for which they are listed. They also accept Edelbrock

valve covers #4449, #4649, #4249 or #4248.

Exhaust Headers: Any header or manifold designed to match the Fel-

Pro #1405 exhaust gasket will fit Edelbrock E-210 Cylinder Heads. The

exhaust ports are CNC profiled to match the Fel-Pro #1405 exhaust

gaskets which are recommended for this application. Edelbrock makes

emissions-legal Tubular Exhaust Systems for many applications. Check

the Edelbrock catalog for complete listing, or call our Technical Hotline.

Rocker Arms: Stock (stamped) type rocker arms will require +.100"

longer-than-stock hardened pushrods (Edelbrock #9629) to maintain

proper geometry. The valve springs supplied will accommodate valve

lifts up to .575" on the #5085 and .650” on the #5087, which is much

higher than stock rocker arms will allow. Long-slot stamped or roller

rocker arms will be required if your camshaft has more than .480" lift.

CAUTION: Some Chevrolet V8 cylinder heads are factory

equipped with "self-aligning" rocker arms. These rocker arms

have a stamped recess on the valve tip end to guide the rocker

arm on the valve stem which allows the rocker arm to guide the

pushrod. Edelbrock cylinder heads are equipped with

hardened pushrod guideplates. Therefore, non-self-aligning,

stamped (i.e., Crane #11801-16, Sealed Power #R-865R,

Pioneer-Barnes #818001 etc.), or non-self-aligning roller

rocker arms are recommended.

INSTALLATION PROCEDURE

Installation is the same as for original equipment cylinder heads. Consult

service manual for specific procedures, if necessary. Use Edelbrock head

gasket #7310. #7310 has a flattened steel O-ring around each bore and

will provide an excellent, long lasting seal. However, it will compress the

aluminum and you must use #7310 for subsequent gasket changes to

get a good seal.

NOTE: YOU MUST DRILL “STEAM HOLES” IN CYLINDER HEADS

FOR 400 ENGINES (See Figure 1): Drill three .125" holes in each

head using 400 c.i.d. head gasket as a guide. DRILL ONLY THE

THREE LOWER STEAM HOLES (closest to the spark plugs) as

indicated. Drill straight into the head (90° from the deck) until the

drill breaks through into the water jacket (about 9/16").

IMPORTANT NOTICE

These cylinder heads are equipped with valve spring cups. Due to the

diameter of the valve spring cups, it may be necessary to clearance the

headbolt washer #1. The #1 headbolt is called out in your instruction

sheet (see figure 3). The headbolt washer in the #1 location is the only

washer that may require clearancing. This will allow the headbolt

washers to seat properly to the cylinder

head

(See Figure 2)

. This can also be

accomplished by removing the valve

spring and cup. Then position washer

prior to installation of cylinder head.

Be sure that the surface of the block and

the surface of the head is thoroughly

cleaned to remove any oily film before

installation. Use alcohol or lacquer

thinner on a lint-free rag to clean. Apply RTV silicone or ARP thread

sealer to head bolt threads, and apply engine oil or ARP lubricant to the

head bolt washers and underside of bolt heads. Torque bolts to 65 ft./lbs.

in three steps (40-55-65), following the factory tightening sequence

(See

Figure 3)

. Check to make sure engine has proper grounds to chassis.

When pouring coolant back in the radiator make sure to use at least a

50/50 mixture of coolant to water. A re-torque is recommended after

initial start-up and cool-down (allow 2-3 hours for adequate cooling).

Other Assembly Tips: When installing the spark plugs and exhaust

manifolds, be sure to use a high temperature anti-seize compound on the

threads to reduce the possibility of thread damage in the future.

NOTE: Torque spark plugs to 10 ft.-lbs. Do not overtighten

sparkplugs! If short reach plug is used, poor performance

and possible engine damage may occur.

PUSHROD GUIDE PLATE ALIGNMENT

Complete Edelbrock cylinder heads are sold with the pushrod guideplates

and rocker studs installed, but they will require checking for proper valve

train alignment and pushrod clearance before operating engine. The

pushrod guideplates are attached to the cylinder heads with two (each)

rocker studs. There is enough clearance around the stud holes to adjust

the guideplates for optimum alignment of your valve train components

(See Figure 4)

1. After the heads have been bolted on your engine and torqued to

specs, install your pushrods, rocker arms, and rocker arm adjusting

nuts.

2. Check pushrod-to-cylinder head clearance.

NOTE: YOU MUST CHECK TO ENSURE THAT THERE IS

CLEARANCE BETWEEN THE PUSHRODS AND THE CYLINDER

HEADS (.005" min.) (See Note "A", Figure 4).

3. If adequate clearance exists between pushrod and head, slowly turn

engine over through at least two revolutions while watching

pushrod. Make sure that pushrod does not rub on the head either at

full lift or when the valve is seated closed.

4. If pushrod rubs on the cylinder head, remove rocker arms, loosen

the rocker studs and move the guideplate as needed to provide

clearance.

5. After checking all pushrods for proper clearance, ensure that the tip

of the rocker arm is making adequate contact with the top of the

valve stem.

6. Carefully re-torque to 45 ft.-lbs. any rocker studs that were

loosened. Check alignment again to be sure that the guideplates did

not move while torquing the studs.
